Bored in a long car ride, needed something to do. Made this. These are just my general opinions on tiers as seen by me.
This tier list is my rating on top lane champions AS SEEN BY ME! Everyone sees lanes and such different so everyone will have their own different tier lists. This is just mine. Their is no specific order within the tiers on the champions, it is just a general categorization.
* means they are on borderline to going down and I'm on the edge with them.
^ Means I'm on the edge and could easily cave in on moving them up a tier.
Some strong common picks. They can usually do pretty well no matter who they fight. They typically can do well at all points in the game.
Tier 1: Nidalee, Riven, Irelia, Nautilus, Kennen, Udyr, Yorick, Malphite, Jax, Lee Sin, Kayle, Olaf, Rumble
Some picks that can be picked early on, but should not be first picks. They are typically centeralized around 1 point of time in the game.
Tier 2: Shen, Jayce^, Lulu*, Poppy, Draven*, Fiora, Graves, Jarvan IV,Pantheon, Renekton, Singed, Corki, Urgot*, Vayne, Vladimir, Xin Zhao^, Warwick, Wukong, Cho'Gath^
These are more of "counterpicks". If you try and pick these before your enemy does you will get countered easily, but if you pick these after your enemy picks you can have some success.
Tier 3: Nunu*, Trundle, Darius^, Gangplank, Shyvana, Garen*, ,Nasus*, Tryndamere, Janna, Maokai, Sion, Sivir, Ezreal, Taric, Teemo, Viktor*, Volibear, Blitzcrank*,Diana,Akali^
These are more of last resort comp specific picks. They can be picked if you are trying to work with your team towards a specific strategy. Their matchups are bad for the most part.
Tier 4:Dr.Mundo, Nocturne, Hecarim^, Leona, Master Yi, Talon, Skarner
